Eastwood sells a version of a rattle can you fill and pressurize yourself. It`s about 35 bucks? Fill it with your car color and away you go! Prep is the word, start with a good clean surface.
I had one of those, it did not lay down paint very well. I have used with a lot of success a product called Preval which is a self loadable bottle for mixing your own paint, it comes with a precharged spray cylinder. I have seen them sold a lot of places, they usually go for about $4 each. Just get your local paint shop to mix up some good paint for you, add reducer and/or hardener any you have real paint!
